let work of person B be x,
let work of person A be x+20÷100
then, 110 = x+ ( x + 20÷100)
110= 2x+1/5
110= (10x+1)/5 taking lcm
110×5=10x+1
550=10x+1
550/10=x+1
55-1=x
x=54

The work done by B is 50 units.
Given,
A works 20% more than B.
Total work = 110.
To Find,
Work of B.
Solution,
In the question, it means that A is 20% more efficient than B.
So,
We will use the formula:
Let the efficiency of B be 100.
Then,
The efficiency of A = 100 +20% of 100 = 120.
The ratio of work done by A and B = 120:100 = 6:5.
total work done is 110 units.
So,
work done by B = × 110.
= 50 units.
The work done by B is 50 units.
